Dame Sancho would be better if she cared less. I am her barometer- if a sigh escapes me, it is answered by a tear in her eye; I oft assume a gaiety to illume her dear sensibility with a smile- which twenty years ago almost bewitched me; and mark! after twenty years enjoyment, constitutes my highest pleasure!
(from vol 1, letter 53: 24 Oct 1777, to Mr S___).
